Shopify apps and e-commerce integrations
Embedded apps, OAuth and app lifecycle, GraphQL Admin API, and getting store data somewhere it can actually be reported on.
Available · ~20 h / month · async

02
An LLM feature in production since 2023 — not a prototype. Prompts that stay stable, failures that degrade gracefully, output a user can trust.

Multi-tenant sync that survives being re-run: idempotent writes, watermarks, leases, no duplicates and no silent drift.
I’m the person who gets handed a backend nobody else wants to touch — and makes it behave.
Nine years at Qualia as the backend and API specialist: a no-code predictive analytics SaaS where I owned both the PHP API and the Python model service, a royalty and settlement platform built from scratch, and outsourced work for a national broadcaster and a university.
